Why does the Xiaomi Outdoor Camera CW700S produce a whistling sound during voice calls?
The whistling sound is an audio phenomenon that occurs between audio devices when sound emitted from a speaker is picked up by a microphone. During calls, try to keep the phone and the camera at least 10 meters apart to avoid echoing and whistling.
For your reference, here are more details about the whistling sound:
1. The sound happens when the microphone captures the sound from the speaker, amplifies it, and then sends it back to the speaker, creating a closed-loop effect. This feedback loop can continuously amplify the sound, resulting in a sharp, screeching noise;
2. The whistling sound is encountered in phone calls, conference audio systems, public address systems, and similar settings, especially when volume levels are set too high or devices are placed too close together;
3. To avoid this issue, you can lower the volume, adjust the distance between the microphone and speaker, or use earphones to isolate the sound.
